 ## Testing
+We created automated tests using **Vitest** and **React Testing Library** to verify some of the main functionality

+- Adding and removing favorite tracks, including saving them in 'localStorage'
+- Search input and clearing the search field
+- Filter interactions
+- Playing and pausing track previews
+- Spotify links and URI conversion
+- Spotify API requests, returned data, and error handling
+- Track card interaction and active state
+- Snapshot testing for the search bar
+
+External API requests are mocked in the tests so they can run without depending on Spotify being available.
